Hi WebKit-dev,
I'd like to ask for WebKit's official position on CSS Module Scripts, as described in the explainer at [1]. This proposal allows developers to import a CSSStyleSheet using the same import mechanism as JavaScript Modules: import styleSheet from "./styles.css" assert { type: "css" }; The proposal has already been in discussion for a while now (long thread at [2], see also the TAG review [3]), but I think it would be useful to have WebKit's official position on it. Note that use of CSS modules will now require a type: "css" import assertion [4] to prevent the MIME type security issue raised at TPAC 2019 [5]. The CSS Module Script HTML Spec PR is at [6], and is currently blocked on resolution of an open issue [7] in the import assertions TC39 proposal. However import assertions is at Stage 3 so that proposal is unlikely to undergo significant changes.
